A polarization separating filter, which can be integrated into a planar hollow waveguide circuit, is comprised of a central hollow waveguide (1), in which two orthogonal, linearly polarized waves can be propagated, where one end of the central hollow waveguide (1) is closed by a short circuit wall (2) and in the vicinity of the short circuit wall (2), two waveguides (3, 4) are coupled to two opposing walls of the central hollow waveguide (1), in an at least approximately identical cross sectional plane extending perpendicular to the longitudinal axis of the hollow waveguide. The hollow waveguides (3, 4) coupled at the end of the central hollow waveguide (1) are rotated in relation to each other in terms of their cross sections so that the fields in them are oriented orthogonally to each other.
